12 Claims.

This invention relates to slider units adaptable for use on separable fastener stringers employing what is known as double action scoops. More particularly, the invention relates to units of this kind employing apertured or ring like bodies havcoupling the fastener stringers beyond the limits of said ends of the body while maintaining the stringers spread beyond the limits of the opening therein. Further in providing within said' ring like bodies tubular guides having pivotal or more or less universal mountings within the body in supporting and guiding a member passed through said ring like body. Still further, the invention relates to ring like or hollow bodies having antifrictional means for supporting and guiding said bodies at opposite sides thereof over tracks or runways, and further to hingedly coupling side portions of the body to form hingedly coupled parts thereof.

The novel features of the invention will be best understood from the following description when taken together with the accompanying drawings, in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views; and in which:

The slider units forming the basis of this application are substantially of the general type and kind disclosed in my prior applications 466,746 led November 24, 1942, Patent No. 2,344,049, issued March 14, 1944, and 468,759 led December 12, 1942. In other words, the slider units are adapted for mounting on stringers having double action scoops to move along the stringers in maintaining an opening of given dimensions intermediate the dual sliders of the unit. One illustration or use of the invention is to provide a guide for the barrel of a gun in its movement through the slot or aperture in the turret of an airplane, tank or similar apparatus, keeping the slot or opening closed at both sides oi the gun barrel. y

The present invention deals still more particu larly with a swiveled or universally mounted guide within the slider unit for guiding and supporting the gun barrel or other member, and to provide swinging or universal movement of the barrel or member within the frame or body structure `of the slider unit. Further, the invention deals with the provision of anti-friction guides for the unit over tracks or runways to provide freer movement oi' the slider unit longitudinally of the slot or opening controlled by the stringers opened and closed by said unit. Still further my invention deals with a slider unit body composed of separate parts having a hinged mounting on the shafts or stubs. forming supports for said rollers or other anti-frictional devices.

Considering the structure shown in Figs. 1 to 3 inclusive, lkepresents a slider unit movable along two str1 gers I2, I2', having interengaging double action links or scoops I3 adapted to be coupled beyond the limits of the body II by more or less conventional sliders I4, I 4', having a pivoted or other mounting, as at I5, I5', so that the sliders may be free to swing in compensating for curvatures in the wall structure I6 of a turret or other supporting part, which is shown in section, in Fig. 3 of the drawings. The stringers I2, I2', control an elongated slot or opening I1, formed in the turret wall structure I6.

The body II is composed of two similar side 4portions I8, I8', having overlapping apertured lugs I9, I9', at the ends thereof to receive stub shafts or pins 20, .20', which form hinged pins or pintles providing relative swinging movement of the parts I8, I8', to further compensate for irregular or sharp curvatures in the turret wall structure. Riveted to the inner ends of the pins Y 20, 20', as shown at 2U" is an elongated tube 2l, and the pins 20, 20', form a swivel mounting of this tube in the body I I so that the tube is free to swing on the pivots 20, 20', within said body, thus providing independent movement of a gun barrel into different angular positions while maintaining a more or less definite line of travel through the slot or opening I1.

' The ends of the pins zo, zo', project beyond the outer lugs I9, and mounted thereon are anti-friction rollers 22 retained against displacement by the like 21 therein, through which the screws 25 pass, and the tapes of the stringersy I2, I2', are stitched, 28', and' cemented, 26", to the supporting strips 28. 26a'.

It will also ,appear from a consideration of Fig. 3 of the drawings that the stringers, including the strips 28, 26a, fold at the pivoted or hinged sides of the body II, and are guided and spaced by the tube 2|.

In the construction shown, the two similar halves I8, I 8'. of the body II are each formed of Itwo-parts 28 and 29, bolted or otherwise secured together as indicated at 38. The purpose of this is solely for simplifying the formation of the castings.

Figs. 4 and 5 of the drawings show a slight modification of the construction shown in Figs. 1 to 3, which disposes with the pivoted separate parts I8, I8', and also the use ofthe guide rollers 22. In this construction a one-piece body 3| is employed, to the contracted ends of which are swivel mounted sliders 32. With this construction the tubular guide or supporting body 33 has its pivot' or swivel pins 34 retained against displacement from the body 3| by detachable plates 35. This type of slider unit is intended for uses where the unit is traveling along more or less straight paths or over supports having slight curvatures.

In Figs. 6, 'l and 8 is shown another adaptation of the invention which differs primarily from the structure shown in Figs. 4 and 5, in providing what might be termed a more or less universal mounting of a central tubular body 36, or in providing what is commonly referred to as a binnacle mounting.

In this construction 31 represents the slider body having at the ends sliders 38 pivoted as at 39 to swivel pins 40, thus providing a nore or less universal mounting of the sliders in the ends of the body 31. Supported in the aperture 4I of the body 31 on pivot pins 42 is a ring like liner 43, the pins 42 being held in place by retaining plates 44. The pivot mounting at 42 provides swinging movement of the ring 43 in one direction, that is to say, transverse to the travel of the body 31. Plvotally supported 'to the ring 43 at right angles to the pins 42, as at 45, is the center tube or guide 38.v

It will thus be seen from a yconsideration of Figs. 1 and 8 of the drawings that this tube or guide 38 is capable of the dual swinging motions within the body 31, providing what might be termed a true universal movement along the barrel of a gun to swing laterally as well as to tilt longitudinally of the slot or aperture in the turret.

In Figs. 9 and 10 of the drawings is shown a still further adaptation of the invention wherein a bulged or partially cylindrical body 48 is formed centrally of a tubular guide member 41 to form a ball like seating in a correspondingly formed socket 48, provided between separable parts 49 .and 58 of a slider body unit.

The part 50 being in the form of a retaining ring facilitating attachment and detachment of the member 41. The ring 5l has projecting apertured ears 5I, facilitating attachment to the primary part 49 by screws or other devices 52, note Fig. 9. With this construction the sliders 53 have the same mounting in connection` with the ends of the body part 49, as shown in Fig. '7.

In Figs. 11 and 12` of the drawings is shown a. further adaptation oirthe invention incorporating, the slider body generally of the structure shown in Fig. 4, modied to the extent to include bracket portions for pivotally supporting shafts adjacent the slider elements, the shafts carrying at their ends rollers which operate in guide channels, in supporting and guiding the slider unit in connection with the turret body in such manner as to take 'both inward and outward thrust to which the stringers may be subjected in movement of the gun barrel through the pivoted guide, as the barrel is moved longitudinally of the slot controlled by the stringers. In this construction the barrel guide is also moved to the extent of incorporating domed portions on opposite sides of the barrel guiding sleeve to combine to some degree the straight tube structures, as in Figs, 1 to 3, with the barrel structure as in Figs. 9 and 10.

In Figs. 11 and 12, the slider unit is generally indicated by the reference 54. As above stated the body 54 is generally of the contour of the body shown in Fig. 4, except that the elliptical opening 55 is extended to form a greater ellipse, and pivoted in opposed narrow walls of this e1- liptical body on pivots 56 is a tube 51, forming a guide for a gun barrel partially shown at 58. The pivots 56 are held in place by retaining plates 59, as with the structure shown in Figs. 4 and 5. The tube 51 includes at opposite side portions thereof outwardly bulged or domed portions 60, which merge with the side walls of the tube 51 but which extend to substantially fill the greater elliptical contour of the opening 55.

'Ihe end portions GI of the body 54 are contracted, and provided with elongated slots 62 which open outwardly through said ends to provide quick mounting of slider supporting studs 63 in said ends. The studs 63 have heads 64 which operate in channels 85. 'I'he nuts 56 of the studs retain key washers 61 in countersunk recesses 68, which retain the studs against displacement from the ends 6 I.

Slider elements 69 are provided with raised ears 10 through which the studs 53 are passed, cotter or similar pivot pins 1I for pivoting the slider elements to said studs.

The slider elements 69 are of more or less conventional construction, and serve to couple and uncouple the links or scoops 12 of stringers 13, 14, note`Fig. 12, the tapes of the stringers being attached to the frame-work 15 of the turret through supplemental tapes 16.

Opposed side walls of the slot or opening in the turret 15 -have inwardly extending flange portions fashioned to form countersunk stringer supporting shafts 11, terminating in inwardly directed flanges 18 in connection with which are supported guide rails 19 of channel cross sectional form. The strips 16 are secured to the shelves 11 by bolts 80. which first pass through facing strips 8i, then through eyelets on reinforced edges of the tapes 16, as indicated at 82, through the shelves 11 and then through reinforcing angle irons 83 which also serve to reinforce the ange portion 18.

At the end portion 6i of the body 54 and inwardly of the slider 69 are downwardly extending brackets 84 having offset end portions 85 arranged beneath the slider/69, as clearly indicated in Fig. 11 of the drawings. Mounted in the end 3. A slider unit for separable fastener stringers havinglinks, said unit comprising a hollow body,

portions 85 are pivot pins 86 which pass through 7movement of the barrel within the limits provided for such movement of the barrel within the body I, whereas the pivot of the tube 51 will compensate for different angular positions that the barrel may assume with respect to the slot of the turret as the barrel moves longitudinally of the slot, and particularly where the barrel moves through a long slot, and when the contour of the turret wall is not on a radius common to the axis of swinging movement of said gun barrel. In this latter movement the barrel also slides through the sleeve or tube 51, and in these differential movements the guide shafts or rods 81 operate in the channel rails 19 to care for inward and outward thrust towhich the unit 54 may be subjected, thus relieving stresses or strain upon the stringers 13, 14, and the mounting tape 16.

In all forms of construction disclosed, it will appear that in each instance the slider body ini cludes a tubular guide and supporting member in the aperture of said, body, which has a pivotal or swinging movement in at least one direction, and that the sliders at opposed ends of the body have in like manner a swinging movement in at least one direction. These various movements compensate for the travel of the unit through openings formed in wall structures of a turret or other support which may have varied `Patent is:
